Frequently Asked Questions

How many internal links should be on a page?

There's no single magic number, but a common guideline is 3-5 relevant internal links per 500 words, or roughly one link every 150-200 words. However, the focus should always be on relevance and user value rather than hitting an arbitrary count. Quality and context matter more than quantity.
